Answer:
C. 12
Step-by-step explanation:
Find the percentage of him drawing a blue marble. 
4/10 = 0.4
He has a 40% chance of picking blue. 
Find 40% of 30. 
12
He would draw a blue marble around 12 times. 
 
        
                    
             
        
        
        
The answer is 12 because you put -3 in the C places which gets you 9 – -3 and then you follow the signs which you would have to add them and get 12

Answer:
   y +2 = 2(x +3)
Step-by-step explanation:
The equation in point-slope form for a line with slope m through point (h, k) is ...
   y -k = m(x -h)
The slope of your given line is the coefficient of x, -1/2. The slope of a perpendicular line will be the negative reciprocal of that: -1/(-1/2) = 2. So, you have m = 2, (h, k) = (-3, -2), and your desired equation is ...
   y -(-2) = 2(x -(-3)) . . . . . . which can be simplified to ...
   y +2 = 2(x +3)
